SVBONY SV240 Telescope Filter, 2 Inches Multi-Narrowband Galaxy Nebula Filter Bundle with SV241 Pro Astronomical Telescope Power Management Box, Remote Control for Astrophotography

1.The multilayer coating design for the remarkable performance in tacking light pollution and high transmittance in core wavelength. 2.Near IR (NIR) is blocked up to 1100nm. 3.The strong ability to tacking light pollution up to BORTLE 8 allows. Dual narrowband filters are mainly used for emission nebulae, planetary nebula, and supernova remnants astrophotography. SV240 can be used for both traditional nebulae and galaxies and star clusters. SV241 Pro Astronomical Telescope Photography Power Management Box is a compact, durable power solution with 5 DC outputs, USB ports, and PWM channels for cameras, heaters, and sensors; Suitable for nighttime observation and astronomical photography. Our SV241 Pro Power Management Box's system offers static electricity protection, reverse connection and backflow prevention, plus USB 3.0 and DC filtering. Fuse, voltage, current, and short-circuit protections ensure stable power, while intelligent detection and auto-restart keep devices safe and running smoothly.
